RESTful HTTP API server using Go, Cobra CLI, Go-chi

Description

This is a basic RESTful API server, build with Golang. In this API server I have implemented Cobra CLI for running the API from the CLI and also used go-chi instead of Go net/http.

Installation

• git clone git@github.com:Neaj-Morshad-101/HTTP-API-server.git

To Run the HTTP-API-server, Please follow the instructions bellow:

Step 01: To start the api server, go to the project directory the run the following command:

cd go/src/github.com/Neaj-Morshad-101/HTTP-API-server/

./HTTP-API-server start -p 8080

Notes: You can give any port number just remember this to use it in request you send.

Step 02: Start Postman by using the command:

postman

Step 03: Now hit the api server using the login info:

curl -X POST -d '{"username":"Neaj Morshad","password":"1234"}' http://localhost:8080/login

Notes: You can do it from the postman also, select verb POST and hit http://localhost:8080/login in the body section: select raw and the these login data in json format

{ "username" : "Neaj Morshad", "password" : "1234" }

Step 04: Set the token from the command line using the following command:

TOKEN="eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOlsiTmVhaiBNb3JzaGFkIl0sImV4cCI6MTY3OTY0MjIxOX0.RMoAGj7KGFUtvq3ebpg_3ksQJqy4Q-gA5jAfOF4SCPQ"

Notes: You will find this token in response section (Cookies) in Posman. Name: jwt Value: TOKEN For the posman you don’t have to set any thing. Go to bash, bacause ‘=’ is not supported in fish

Step 05: Now hit the API sever using any commands like this:

curl -H 'Accept: application/json' -H "Authorization: Bearer ${TOKEN}" http://localhost:8080/albums

Notes: You can hit the API using postman also, Select correct verb and the API endpoints (GET, PUT, POST, DELETE)

Build the docker image using these commands:

• docker build -t neajmorshad/http-api-server:0.0.1 .
• docker push neajmorshad/http-api-server:0.0.1

Run the API server from the docker image in docker container

• docker run -p 8080:8080 <image_name> (valid when used CMD ["start", "-p", "8080"] in Dockerfile)
• docker run -p 8080:8080 <image_name> start -p "8080" (when did not used CMD in Dockerfile)

---

Upload the image to Docker Hub

• docker login --username=<docker_hub_username>
• docker tag <id_of_the_created_image> <docker_hub_username>/<name_of_the_image>:<tag>
• docker push <docker_hub_username>/<name_of_the_image>:<tag>

---

Run using volume (where did not gave .env file in docker image)

• docker run -v <absolute_host_path/.env>:<container_path/.env> -p 8080:8080 <image_name> start -p 8080
